The objective of this work being to study and simulate the association of a photovoltaic panel using the MPPT command, which controls the DC-DC converter ensuring the power interface of the photovoltaic generator and the load, supplying an asynchronous machine from a DC/AC converter controlled by a flux-oriented command.
We will first approach the principle of operation of a photovoltaic panel, secondly we will represent a preliminary study of the DC-DC converter used in the photovoltaic conversion chain, which will also be the subject of modeling and we will present the main search algorithms for the maximum power point of the photovoltaic source.
In the third part, we study the motor-inverter association, starting with the modeling of the machine in the Park frame then the association of the MAS-Voltage inverter controlled by a flux-oriented command at no load and at load then their simulation results using Matlab/Simulink software. The analysis of the simulation results of this control approach clearly shows that the system perfectly follows the reference values and, consequently, provides a good static and dynamic performance of the machine under study Justify
